Abstract: The present invention relates to an artificial sign stone and a manufacturing method thereof. In accordance with the present invention, an artificial sign stone replacing a natural stone is manufactured to prevent color and shape changes even after a long use. Since the artificial sign stone is manufactured with a mold to eliminate the need to separately process an exterior or front characters, the artificial sign stone can be easily manufactured and processed, and can be priced low. Since 35 to 45 parts by weight of thermosetting resin per 100 parts by weight of a raw material composed of 70 wt% of marble pieces with a particle size of less than 1 mm and 30 wt% of charcoal powder are mixed and then hot-pressed, the artificial sign stone can have the same texture and color as natural sign stones. Since the artificial sign stone uses charcoal, the artificial sign stone can have effects of charcoal components such as strong dehumidification and humidity control, odor removal, absorption of various chemicals, oxidation prevention, electromagnetic wave blocking, negative ion emission, and far-infrared radiation emission effects. In particular, the artificial sign stone can absorb radon, which is a harmful chemical substance generated in the ground, to prevent damage to a human body. Since the artificial sign stone using charcoal is very light, the artificial sign stone can be easily transported. The artificial sign stone using an LED lamp can have an effect of excellent identifiability at night.

Therefore, the cleanliness, pleasantness, and disinfection efficiency of the internal air can be increased. The internal air current is allowed to form a vertical direction, so the ventilation efficiency can be increased. In addition, the polluted internal air can be rapidly discharged to the outside, thereby effectively preventing the spread of infectious diseases such as viruses and maximizing disinfection efficiency. In addition, the conventional problem that the internal air current is formed in a horizontal direction and the virus infection rate is high can be innovatively solved. In addition, the discharge position of the internal air can be moved as higher as possible from the height of the breathing of the human body, thereby preventing surrounding people from coming in contact with the discharged internal air. Therefore, the disinfection efficiency can be improved more, and the air pollution can be reduced.
